这是我的输出
R7 (07h) 8 ALRSWAP 0 Left/Right ADC Channel Swap Audio Inte**ce
Audio 1 = Swap left and right ADC data in audio Control
Inte**ce inte**ce
0 = Output left and right data as normal
7 BCLKINV 0 BCLK invert bit (for master and slave modes) Audio Inte**ce
0 = BCLK not inverted Control
1 = BCLK inverted
6 MS 0 Master / Slave Mode Control Audio Inte**ce
0 = Enable slave mode Control
1 = Enable master mode
